iPhone 5C battery drains fast
I have an iPhone 5C it works great but I noticed that the battery is draining fast. I thought it was normal because it is an older phone and running new iOS. I tried putting it in low power mode but it didn't help. I charged it to 100% and without being used its dropped nearly 40% battery. It was on 88% and I powered it down and waited about 5 minutes and turned it back on. It was at 80%. I tested the battery with my computer with the Coconut battery application and it says that the battery is good and at about 80+% capacity. Anyone know anything about this or how to fit it?
